Description
Technical Field
The utility model relates to a wind generating set impeller equipment fixing device belongs to aerogenerator erection equipment technical field.
Background
At present, wind power plants in the new energy field of China are developed rapidly, and wind power plants in mountainous areas occupy a considerable proportion. With the continuous updating and progress of wind power technology, the capacity of a single machine is larger and larger, fans of more than 3MW are installed in wind power plants in mountainous areas, and fans of 2.5MW become normal. The large-capacity fan means that the diameter of an impeller is larger, the height of a hub is higher, and the large-capacity fan brings greater examination and difficulty to hoisting of a wind power plant in a mountain area. Particularly, in the conventional hoisting mode, one main crane is matched with two auxiliary cranes to complete the assembly operation, and a large enough platform is difficult to provide in narrow mountainous areas with very limited space, so that the ecological influence is large and the cost is high.
Disclosure of Invention
An object of the utility model is to provide a wind generating set impeller equipment fixing device. The device only needs one to assist and hangs can accomplish assembling of impeller, the narrow and small problem in solution mountain area wind-powered electricity generation field place that can be better.
The technical scheme of the utility model: the utility model provides a wind generating set impeller equipment fixing device, is including setting up 1 reinforced concrete cylinder in fan basis border position department, and the reinforced concrete cylinder is vertical upwards to be set up, and its top surface is fixed to be provided with pre-buried anchor bolt ring.
In the device for assembling and fixing the impeller of the wind generating set, the reinforced concrete column is a hollow column.
In the device for assembling and fixing the impeller of the wind generating set, the wall thickness of the hollow cylinder is more than or equal to 1 m.
In the fixing device for assembling the impeller of the wind generating set, the top surface of the reinforced concrete column is 0.5m higher than the ground.
The utility model has the advantages that: compared with the prior art, the utility model discloses a set up 1 reinforced concrete cylinder at fan basis edge, there is pre-buried anchor bolt ring at cylinder top fixed mounting, fan tower section of thick bamboo hoist and mount are accomplished the back, at first be fixed in pre-buried anchor bolt ring with impeller wheel hub hoist and mount with a small-size crane, then assemble 3 blades on wheel hub, accomplish the whole back of assembling of impeller on ground, a rethread owner hangs can be with impeller integral hoisting to tower section of thick bamboo top, the intermediate process need not assist and hangs equipment, crane station space has been saved greatly. The whole device has the advantages of simple structure, strong practicability, low investment, safety and reliability.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic top view of the structure of fig. 1.
Reference numerals: 1-pre-buried anchor bolt ring, 2-reinforced concrete column and 3-fan foundation.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
The embodiment of the utility model provides a: a wind generating set impeller assembling and fixing device is shown in attached figures 1-2 and comprises 1 reinforced concrete column body 2 arranged at the edge of a fan foundation 3, wherein the reinforced concrete column body 2 is vertically and upwards arranged, and the top surface of the reinforced concrete column body is fixedly provided with an embedded anchor bolt ring 1.
In the installation process of the device, after the fan foundation 3 is poured, the pouring of the reinforced concrete cylinder 2 and the installation of the embedded anchor bolt ring 1 are completed. When the impeller hub is used, after the fan tower cylinder is hoisted, the impeller hub is hoisted by a small crane and is horizontally placed at the top of the reinforced concrete cylinder 2, the bolt on the embedded anchor bolt ring 1 penetrates through the bolt hole on the hub base, and then the hub is fixed on the embedded anchor bolt ring 1 through the nut. Then, 3 blades are sequentially lifted by a crane and then assembled on the hub. After the impeller is integrally assembled on the ground, the impeller is finally hoisted to the top of the tower barrel through a main crane for installation, auxiliary crane equipment is not needed in the middle process, and the space of a crane station is greatly saved.
The reinforced concrete column 2 is a hollow column, so that the construction cost can be reduced. The number and the specification of the bolts on the pre-buried anchor bolt ring 1 are determined according to the hub interface.
The wall thickness of the hollow cylinder is more than or equal to 1m, and the hollow cylinder is guaranteed to have enough strength supporting capacity.
The top surface of the reinforced concrete column 2 is 0.5m higher than the ground, so that the impeller assembly is prevented from touching the ground in the installation process, and the impeller assembly is convenient to install.
